My invention relates to window construction and the-main object of the invention 1sto provide such a construction which includes housing means arranged or built in the wall f curved spring means on said track means to provide a slidable air tight fit.

Other objects and advantages are attained with my invention, as will become apparent from the following descriptiontaken -in connection with the accompanying drawings, forming part of this specticatiomand in which, y

Fig- 9 is a vertical cross sectional view 011 line 9 9 of Fig. 8.

In the drawings I have illustrated the preferred form of my invention which comprises housing means 12 arranged and placed in the wall 13 'of a building, along the sides of the window, and forming a part of the .window frame and beingconnected to the the housing, and a suitable sash 22 is placed over. member 21 and fastened with a few screws 23 on said corner member 17 of the housing, to engage at the inward side of the sash. lThis strip may thus be readily taken olf. to permit convenient removal of the sash, from the window.

The sashis provided in any desired style or design, single or double, and its side member 16 1s arranged to fit closely`but slidably in the slot of the housing. A re# enforcing plate 2'4 is fastened .to the side edge of said member 16', and preferably has a rib 24 set tightly in a groove in member 16' ,thus forming an air tight fit; and furthermore a curved resilient member 25,I preferably a strip of spring bronze, is fastened to lsaid plate and slides therewith in the housing, being arranged to closely engage the window frame and form an air tight fit therewith. W ith the use of two sashes in the window, one is lprovided at the meeting edge with a channe member 26, and the other with a rib 27 closely fitting therein; and an overlapping flange 28 on one sash lits snugly 1n a corner groove in the other sash, while a closing strip 29 covers the outer joining edges of the two sashes, thus providing a positive air tight: and storm tight fit.

,Iprovide improved track means, preferably at the topand bottom of each sash and on the Window frame and housing, to provid' guide means and a support for easily sliding the sash. This track means preferably includes a plate 3() fastened under the top member of the housing and under the top member of the window frame, said plate having a rail or rib 31 thereon which is embracedfby a companion channel member 32v mounted on the top of the sash'. Curved resilient -members 33, preferably strips of spring bronze, are placed between' members 31 and 32, as by being fastened on the rail, and closely but slidably engaging the channel member', so as to form an airtight tit. The lower track means preferably includes a rail 34 fastened on the window stool 35 and on thevbottom member of the housing, and also a channel melnber 36 which is set'into thebottom edge of the sash; furthermore a pair of casings 37 are set into said bottom of the sash and contain a shaft 38 with an inner wheel 39 mounted thereon and forming a large axle for an outer wheel 40 rotating thereonwith .the use of antifriction bearings 41 and traveling along rail 34. Side flanges 'rou 42 on said casing extend along 4the sides of the rail; and curved resilient members 43, preferably of spring bronze, are mounted on the rail and slidably engage the channel member to form an air tight tit, between the sash and the window stool.

It is apparent from-the above disclosure that I have provided a construction wherein the Window is moved out of the window opening so as to entirely clear said opening for the entrance of fresh air, and also that the window sash is entirely concealed and protected in the housing and out of the Way, being thus a vast improvement over the usual Casement windows or swingable windows, and also over the usual slidable sashes which slide upon one another thus clearing only one-haltl of the window opening; and it is also apparent that an air tight and storm tight fit is formed with this construction, and especially with the curved spring strips used at the connections of the various members.

What I claim as my invention and desire to secure by Letters Patent is:

1. A. window construction comprising housing means consisting of frame members and connecting panels therebetween placeable in thev wall and forming part of the window frame, there being a slot in said frame part, and track means with spring strips for sliding the window sash through said slot into said housing means.

2. A window construction comprising a slidable Window sash, and rotary anti-friction means including concentric rollers built and concealed in said sash for readily moving and for supporting said sash.

3. A window construction comprising a housing forming a side part of the window frame, a sash movable sideways thrcugh said frame into said housing, and track means on said sash and said frame and said housing including rail means mortised weather-tight in the frame for readily sliding said sash into said housing.

4. A window construction comprising a frame, sash means movable sideways in said frame, track means including channel means on top and bottom of said sash means, and rail means with curved springs mounted weather-tight on said Jframel en gageable in'said channel means for Slidably guiding and supporting said sash means.

5. A window construction comprising a frame, sash means slidable in said frame, track means including channel means and rail meansA on said sash means and said frame for sliding said sash means, and spring strips between said channel means and said rail means to provide an air tight slidable fit.

6. A window construction comprising a frame, a housing forming a side part of said frame, sash means slidable into said housing, track means on said sash means and said frame and said housing, including channel means and rail means, and spring means between said channel means and said rail means to form an air tight slidable fit therebetween.

7. A window construction comprising housing means built in the wall and forming part of the frame, sash means slidable into said housing means, and a curved spring strip on the side of said sash means, inside said housing, to engage said frame part and form an air tight lit therewith.

8. A win-dow construction comprising a frame, a housing forming a part of said frame, sash means slidable into said housing, track means on said sash means and on said frame 4and housing, including channel means and rail means with curved spring means therebetween to form a slidable tight fit, and curved spring means on the side of the sash means within the houslng, for engaging the frame and form a, tight lit.

9. A window construction comprising a frame and a housing connected thereto, a sash member slidable into said housing, track means including a rail on said frame and housing,curved spring means on said rail, channel means set in said sash and litting closely over said spring means, and casing means including rotary means set in the sash with said channel means, for supporting the sash on said rail, and to travel t'reely thereon.

In testimony whereof I have signed my name to this specification'.
